Here are some warnings we must consider in the transfer window this summer. 1) Do not sign players for large fee's after they have had just one great season in the Premier League. Save big inflated Premier League fees to consistent players who have had at least 2 or 3 strong seasons in a row. 2) Do not just sell or turn against players after they have had just one bad or bellow par season for Liverpool unless they have been a consistent problem/ liability (which what ever you say, no one has). 3) Do not judge players on age. Being over 30 doesn't ruin a player. That applies to selling and buying.
